Because of bitcoind deprecating its internal account system, the getbalance RPC call now has a dummy argument as the first argument. The help says it can be omitted or changed to '*', so we change it to '*', both for backward compatibility and because in testing I found that omitting the argument was broken. Using '*' has the same semantics as omitting the argument, if accounts were not used in the previous version of bitcoind.
